Theory of Helimagnons in Itinerant Quantum Systems IV: Transport in the Weak-Disorder Regime
T. R. Kirkpatrick, D. Belitz, Ronojoy Saha
We apply a recent quasiparticle model for the electronic properties of metallic helimagnets to calculate the transport properties of three-dimensional systems in the helically orde…
Theory of Helimagnons in Itinerant Quantum Systems III: Quasiparticle Description
T. R. Kirkpatrick, D. Belitz, Ronojoy Saha
In two previous papers we studied the problem of electronic properties in a system with long-ranged helimagnetic order caused by itinerant electrons. A standard many-fermion formal…
Analogy between Three-Dimensional Helimagnetic Metals and Two-Dimensional Nonmagnetic Metals: Transport in the Weak-Disorder Regime
T. R. Kirkpatrick, D. Belitz, Ronojoy Saha
We present a quasi-particle model that allows for a simple description of the electronic properties of metallic helimagnets. For weak quenched disorder, we find a leading linear te…
Specific heat of a one-dimensional interacting Fermi system: the role of anomalies
Andrey V. Chubukov, Dmitrii L. Maslov, Ronojoy Saha
We re-visit the issue of the temperature dependence of the specific heat C(T) for interacting fermions in 1D. The charge component C_c(T) scales linearly with T, but the spin compo…
Nonanalytic Magnetic Response of Fermi- and non-Fermi Liquids
Dmitrii L. Maslov, Andrey V. Chubukov, Ronojoy Saha
We study the nonanalytic behavior of the static spin susceptibility of 2D fermions as a function of temperature and magnetic field. For a generic Fermi liquid, χ_s (T, H)= const+c_…
